Building zsmalloc as a module does not work on ARM because it uses an interface that is not exported: ERROR: "flush_tlb_kernel_range" [drivers/staging/zsmalloc/zsmalloc.ko] undefined! Since this is only used as a performance optimization and only on ARM, we can avoid the problem simply by not using that optimization when building zsmalloc it is a loadable module. flush_tlb_kernel_range is often an inline function, but out of the architectures that use an extern function, only powerpc exports it.
